Ramsay Bolton to Theon Greyjoy:

“This isn't happening to you for a reason. Well, one reason: I enjoy it! If you think this has a happy ending, you haven't been paying attention.”

Ramsay Bolton to Lord Roose Bolton (on being asked about Theon):

“We've been flaying our enemies for a thousand years. The flayed man is on our banners!”

Ramsay Bolton to Sansa Stark:

“You should hold onto your candles, the nights are so long now.”

Ramsay Bolton to Myranda:

“Jealousy bores me. You remember what happens to people who bore me.”

Ramsay Bolton to Little Finger (after he drops Sansa at Winterfell):

“I will not hurt her, you have my word.”
